The relationship between nutrient availability and primary productivity is fundamental in ecology. Generally, the more nutrients—such as nitrogen and phosphorus—available, the higher the primary productivity, which refers to the rate at which photosynthetic organisms produce organic compounds. Nutrients support plant growth and, in turn, enhance the food chain. Limiting nutrients can constrain productivity, leading to lower biomass and affecting entire ecosystems. Therefore, managing nutrient levels is critical to sustaining productive ecosystems and maintaining food security.
